Reuters reports that "the U.S. military has ordered increased security at facilities across Europe in the wake of the Paris attacks, but officials on Thursday described it as a precautionary step and said there was no intelligence about any specific threat."

"The Pentagon declined to detail the kinds of measures being rolled out as part of the 'additional force protection measures and random security enhancements' announced by the U.S. military's European Command."

"Such measures could include anything from random searches of individuals entering bases to deploying additional personnel to staff military checkpoints."
